size to pass than whir-h it is snflieiently' smaller so that,

said Fihnft may rotate or slide upon the rod. The lntler ll'ierei'oro nll'orrls a support for {he rear ends of the lelew-opie shafts, n0 nmflzer whnl lheir position within the resin no described below. Then the plate 36 is 'liwl'lflifltl'llfl' from the outer fare of the easi112. the entire rod may he removed theren'ilh so as to permit a separation of parts if it shonlrl become necessary.

With the. nhove r'onstrnr-tion of parts. the operation isms follows: 'Fwo ordinary cans are phu'ed nnrler lhe months 6 and 7 of the easing. the run being for ashes which will Tall from the sifting eompartment S to the left of the partition 8. and the can (3 for siftings or ronl which will fall from the clumping eompartment T) to the right of snirl partition. The ernnk handle 19 is now so that the eeren l ehmcle Within the siftingeompnrtrnenf as shown in Fig. l. the cover 4 is nised. the weight of the hnille 14 causes the screen to stand with at 18 hy' its cover 13 uppermost, and this cover is raised so that a charge of coal and ashes as taken from the furnace is put into the screen. The covers are now closed, and the operator turns the screen by means of the crank hanldle. The ashes are-sifted out of the coal and fall through the screen into the compartment S, and thence through the'mouth 6 into the ashcan A,and all dust raised is confined within the casing. After a suitable time, the operator draws on the projecting handle 29, with the result that both shafts and the screen move along the rod 37 until the rear head 22- strikes the partition 18 around the opening 9 therein and closes the same. Then the operator grasps and draws on the handle 19 until the outer shaft 17 slipsalong the inner shaft 27 and the screen body 10, moves upon the inner shaft with its open end at 12 spaced from the o ening 9 and the head 22, and its closed en or head 11 adjacent the front wall of the casing. There is thus exposed a certain s ace between the mouth of the screen and t e partition, and now when the o erator rotates the screen by its crank han lo the siftings or coal yet within the screen, falls out the mouth-the bafiie assisting in its agitation and delivery-through the compartment D and into the coal can O; and again what dust arises is confined within the casing in a manner which will be clearly understood.

Now by ushing all handles inward as far as possib e, the parts are caused to resume the position shown in Fig. 1, when the covers may be raised and a new charge put into the screen and the operation repeated.

It will be observed that the compartment D- wherein dumping occurs must be longer than the compartment S wherein aiftmg occurs. The latter may only be of a-lengt sufiicient to receive the screen and both its heads, whereas when the screen is drawn into the dumping compartment awa from its rear head, it must be capable 0 being moved suificiently far therefrom to uncover a space out of which the siftings or coal may be delivered. Of course it would be possible to elongate the hearing at 18 and omit the rod 37, but by having the telescopic shafts 17 and 27 both tubular, the bore of the smaller shaft afl'ords an opening through which may pass a rod 37 whose rear end finds support as at 36 on the rear wall of the casing, and therefore the several axial members are very well supported. by simplest means, and yet can be, detached from the casing and removed when desired.

What is claimed as new, is z- 1. In an ash. sifter, the combination with a casing having a partition dividing its interior lnto two compartments of unequal length and provided with a large opening, an outlet at the bottom of each compartment, and a filling opening at the top of the part is rotatably and slidabl smaller comsartment closed by a cover; of a rod secure to the rear wall of the cas ng, projecting centrally through said opening, and extending approximately to the front wall, the latter bemg rovided with a hole concentric with the rod a twoart tubular shaft whose inner part is rotate l and slidably mounted on the rod and w ose outer mounted on the inner part and both of w ich parts extend through said hole, a crank handle on the outer part beyond the front wall of the casing, a screen having a cupped body of a size to pass throu h the opening of the artition, and whose ttom is mounted ri dl on said outer part a closure for the moat of the screen mounted on the inner part and of a size to contact with the artition around the o enin therein when d awn against it, a ha e wit in the screen, and a door in one side of the same registering with the cover in the casing.

2. In an ash sifter, the combination with a casing having a partition dividing its interior into two compartments of un ual size, the partition being provided wit a lar e opening, an outlet at the bottom'of eac com artment, and a filling opening at the top 0 the'smaller compartment, of a rod secured to the rear wall of the casing, pr0- jecting centrally through said opening, and extending approximately to the front wall, the latter being provided with a. hole concentric with the rod, a two-part tubular shaft whose inner and longer part is rotatably and slidably mounted on the-rod and whose outer and shorter part is rotatably and slidably mounted on the inner artand both of which parts extend throug said hole, 21perating means on the outer part be ond e front wall of the casing, a screen wiring a substantially cylindrical body of a size to pass through the opening in the artition and a closed bottom mounted rigi y on sai outer part and, a head for the open end of the screen mounted on the inner part and adapted to close the mouth of the screen and a door in one side of the screen body adaptedto register with the filling opening of the casing. V

3. In an ash sifter,the combination with a casing having a partition dividing its interior into two compartments and provided with a large opening, an outlet at the bottom of each compartment, and a filling opening at the top of the rear compartment closed by a cover and a bearing in its front wall; of a two-{part telesco ie shaftcrotatably and slida 1y mounte bearing, a crank handle on the outer art of said shaft beyond the front wall 0 the casing, a substantially cylindrical screen body, a closed bottom therefor mounted rigidly on said outer art and of a size to pass through the opening in the partition, a

head for the open and of the screen body mounted on the inner part of said shaft and of a size to contact with the jartition around the openingtherein when Yawn against it, and a. door in one side of the register ing with the cover in the casing.

4. In an ash Sifter, the combination with a casing having an upright pswtitiun dividing its interior into twa compartments and 'provid rear wail of the cusin ed with a large opening, an outlet at the bottom of each compartment, and a.-fi1ling opening in the casing; of a guide on the shaft 'fihose inns; an longer garb is rota- @gblga Nd alidably nmunted on t e guide and atwo part tubular whosga outer and shorter part is rotatably and sli'dably mounted on the inner part and. both of which parts extend thmugh the front Wall of said casin handles at the fund; ends of said parts cyond the front wall of ihe casing, a screen having a cupped body of a size in pass izhruugh said npening and a. dosed autism meunted rigidly 01' said outer part, and a clown for the mouth 05 the screen ma ma/d on the inner part and. 0f 2; H
